QB Kyler Murray: The only access to Murray on the field is through stretching and individual drills, so it’s tough to get a true gauge on how he looks, but one thing is for sure: His passes are crisp. They seem to jump off his hand and his long passes land rather effortlessly. His teammates rave about him. They’ve praised his speed, accuracy, intelligence and his leadership — all high marks for the 21-year-old No. 1 overall pick. — Josh Weinfuss

DE Nick Bosa: Getting an early read on Bosa has been difficult after a Grade 1 hamstring strain slowed him in the team’s second OTA. Before that injury, Bosa looked as advertised: He had NFL-ready pass-rush moves, fit in well in the locker room and is expected to contribute right away, according to teammates. “He works very hard,” defensive end Dee Ford said. “He’s a very good guy. You hate to see that [injury] for a rookie because he’s really progressing, and he’s going to be important for this defense, and that D-line room is really starting to mesh. He’ll get healthy and he’ll get back. He’ll be fine. It’s important as a rookie to stay the course. Stay the course, don’t get down. You’ve got a lot of stuff to go through as a rookie. I told him once ball gets here, it’s all about ball. All the extra stuff is gone.” — Nick Wagoner

DE L.J. Collier: Linemen are the hardest players to evaluate in noncontact practices, but there’s been no reason to waver on the belief that Collier can be a contributor right away — at least in a rotational role as an early-down edge-setter and/or an inside rusher on passing downs. He’s taken some reps with the starters and has caught the eye of Pro Bowl left tackle Duane Brown. “I think as a rookie coming in, he definitely has some savviness, some craft in his moves that you normally wouldn’t see from a younger guy,” Brown said. “He’s strong, he’s got long arms, strong player. I think right now with no pads on, it’s hard to assess someone, but I think he’s definitely going to make some plays this year just based on what I’ve seen so far.” — Brady Henderson
